Biography

Dr Valentin Heller is currently an Assistant Professor in Hydraulics in the Department of Civil Engineering at the University of Nottingham and a member of the Environmental Fluid Mechanics and Geoprocesses research group. Before moving to the University of Nottingham in 2014, he held one of the prestigious Imperial College London Research Fellowships working on various experimental and numerical research projects (2011-2014). He worked further as a Research Fellow at the University of Southampton (2008-2011) conducting research into wave energy conversion funded by EPSRC and the EC. His first postdoctoral research took place at ETH Zurich in 2008. ETH Zurich was also the place where he received his PhD for the research project "Landslide generated impulse waves - Prediction of near field characteristics".

Dr Heller is a graduated Civil Engineering (MSc) addressing in his final year project "Ski jump hydraulics", which was awarded the Maggia Price 2004. He further received the Harold Jan Schoemaker Award in 2013 from IAHR for the most outstanding paper published in the Journal of Hydraulic Research in 2011-2012 (Scale effects in physical hydraulic engineering models) and is a member of the Leadership Team of the Committee on Hydraulic Structures of IAHR. Dr Heller is the PI of a project funded by The Leverhulme Trust, the supervisor of the Marie Sklodowska-Curie Actions Individual Fellowship project of Dr Begam and was the project leader of a EU funded HYDRALAB+ project. He was further the PI of a NERC funded project, is an Editor of Landslides (Springer, Impact Factor 4.7), run three Special Issues in the fields of hydraulics and tsunamis and has been a technical reviewer for over 40 academic journals. Dr Heller further gave invited guest lectures/seminars and run or contributed to workshops in China, Germany, Switzerland, the UK, Portugal and Romania and his next invited talk will be a keynote lecture at the 9th International Symposium on Scale Modeling in Napoli (https://issm9.sciencesconf.org) in March 2022.

Current Research

Dr Heller is mainly active in Experimental and Computational Fluid Dynamics with applications into a wide range of fluid-structure interactions from small to very large scale. The fluid is typically water and the structure a hydraulic structure such as a dam, or a (granular) landslide or iceberg. His research team applies a wide range of measurement systems (Particle Image Velocimetry, laser distance sensors, load cells) and open source codes such as DualSPHysics, OpenFOAM, SWASH and LIGGGHTS-DEM. His current research includes the following key areas:

  • Landslide-tsunamis (impulse waves)
  • Scale effects in fluids and granular flows
  • Fluid-structure interaction
  • Machine learning (ANN) in hydraulics

Dr Heller is the PI of the project "Paradigm shift of landslide-tsunami characterisation and prediction" funded by The Leverhulme Trust (RPG-2021-001) and the supervisor of the Marie Sklodowska-Curie Actions Individual Fellowship project "ENSURE: Experimental and Numerical insight into Scale effects in granUlaR slides in the mountainous Environment" (101029080) from Dr Begam. He was the project leader of the EU funded HYDRALAB+ project "Tsunamis due to ice masses: Different calving mechanisms and linkage to landslide-tsunamis" resulting in a publication in Scientific Reports, he was the PI of the NERC funded project "A hybrid investigation of geometrical effects on landslide-tsunamis: Generic hazard assessment and numerical benchmark test cases" (NE/K000578/1) and he was the lead author of the now widely applied landslide-tsunami hazard assessment method "Landslide generated impulse waves - Basics and computation" (recently published in its 2nd edition Evers et al. 2019). He is further an Editor of the Landslide Journal (Springer, Impact Factor 4.7), he run the special issues Tsunami Science and Engineering I and Tsunami Science and Engineering II in the Journal of Marine Science and Engineering (MDPI, Impact Factor 1.7) and the special issue Innovative Model Strategies in Hydraulics in the Journal Water (MDPI, Impact Factor 2.5). He has been a technical reviewer for over 40 academic journals and for four research councils thus far and his article on scale effects received the 17th Harold Jan Schoemaker Award from IAHR in 2013.
